| ○ | ○ | Article | Hot-Pressing Transfer of Diffraction-Grating Perovskite for Efficient Bifacial Perovskite Solar Cells | Compared with monofacial solar cells, the development of bifacial solar cells has garnered considerable attention for achieving higher power output by simultaneously harvesting direct and diffused light while incurring fewer additional manufacturing costs. Perovskite light absorbers, given their outstanding optoelectronic properties, present great opportunities for fabricating bifacial solar cells. However, one of the challenges in designing bifacial perovskite solar cells (PSCs) is that they suffer from optical and electrical losses due to insufficient light absorption in the perovskite layer. In this respect, in this work, a hot-pressing transfer process is developed to fabricate a diffraction-grating (DG) perovskite layer to form a bifacial PSC. The constructed DG structure on the perovskite layer improved its light-harvesting efficiency, reduced its charge recombination, and enhanced its charge extraction properties. The bifacial DG PSC achieved power conversion efficiencies of 14.01% and 10.04% for the bottom and top illuminations, respectively, resulting in a bifaciality factor of 0.71. Therefore, the newly developed hot-pressing transfer process for fabricating DG structures on perovskite layers is a promising technique for fabricating high-efficiency bifacial PSCs with high bifaciality factors. Hot-pressing transfer process is developed to fabricate a diffraction-grating (DG) perovskite layer to form a bifacial perovskite solar cell (PSC). The DG perovskite layer has advantages in improving light trapping and charge extraction properties and reducing the charge recombination. The bifacial DG PSCs outperform monofacial PSCs under concurrent bifacial illumination.image | Muthukrishnan, Akshaiya Padmalatha; Lee, Junyeong; Kim, Jun Yong; Karim, Abrar; Kim, Jongbok; Yoo, Jeeyoung; Do, Yun Seon; Jo, Sungjin | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kumoh Natl Inst Technol, Dept Mat Sci & Engn, Gumi 39177, South Korea; Tabriz Univ, Fac Chem & Petr Engn, Email, Iran | Yoo, Jeeyoung/AAH-1359-2019; Kim, Jung Kyu/C-3271-2012 | 57452543600; 58853044900; 57209837877; 57220672493; 15762365000; 56046607500; 24338060500; 7101724027 | yuns.do@knu.ac.kr;sungjin@knu.ac.kr; | ADVANCED MATERIALS INTERFACES | ADV MATER INTERFACES | 2196-7350 | 11 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 4.4 | 32.8 | 2.24 | 2025-05-07 | 8 | 8 | bifacial; diffraction-grating; hot-pressing; perovskite solar cell; transfer printing | bifacial; diffraction-grating; hot-pressing; perovskite solar cell; transfer printing | Conversion efficiency; Diffraction; Fabrication; Hot pressing; Light absorption; Perovskite; Perovskite solar cells; Solar absorbers; Bifacial; Bifacial solar cells; Diffused light; Grating structures; High power output; Light absorbers; Manufacturing cost; Perovskite layers; Transfer printing; Transfer process; Diffraction gratings | English | 2024 | 2024-02 | 10.1002/admi.202300808 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Isometry property and inversion of the Radon transform over a family of paraboloids | Integral geometry problems involve finding a desired function from its integrals on a surface. These problems are closely intertwined with the generalized Radon transform, and obtaining an inversion formula for it is pivotal in solving integral geometry problems. The applications of integral geometry span various fields, including tomography, radar, and radiology. Particularly noteworthy is the recovery of a function from integrals over a parabola, which holds significance in reflection seismology. In our study, we concentrate on the transform that maps a real-valued smooth function with compact support to integrals over the paraboloid. This transform, along with its dual, can be expressed as convolutions of kernels and given functions, and we have derived inversion formulas based on their isometric properties. | Kim, Jeongmin; Moon, Sunghwan | Seoul Natl Univ, Coll Nat Sci, Dept Math Sci, Seoul 08826, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Math, Daegu 41566, South Korea | 58821818800; 56063426100 | yknowjm21@snu.ac.kr;sunghwan.moon@knu.ac.kr; | FILOMAT | FILOMAT | 0354-5180 | 38 | 23 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2024 | 0.9 | 32.8 | 0 | 2025-05-07 | 0 | 0 | Inversion formula; Paraboloid; Radon transform; tomography | CURVES | Inversion formula; Paraboloid; Radon transform; tomography | English | 2024 | 2024 | 10.2298/fil2423047k | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Large-Sized Hydrogel Sheet Incorporated with Dual Physical Crosslinkers for Enhanced Mechanical and Adhesive Properties | This work reports the fabrication of a large-sized hydrogel sheet with enhanced mechanical and adhesive properties. The fabrication involves the introduction of carboxymethyl-modified cellulose nanofibers (m-CNFs) and solid silica nanoparticles (SSNs) as physical cross-linkers into acrylic acid monomer (AA), followed by bar coating and photopolymerization. The addition of the nanomaterials to the monomer solution renders it viscous, enabling the fabrication of A4-sized hydrogel sheets with uniform thickness and enhanced mechanical and adhesive properties. Interestingly, the combined incorporation of both the nanomaterials generates a synergistic effect to improve the properties much more, which results from the hierarchical rupture of the multiple hydrogen-bonded interactions among the poly(acrylic acid) (PAA) matrix, m-CNFs, and SSNs. Under optimal conditions, the hydrogel sheet incorporated with the dual crosslinkers exhibits a sevenfold higher toughness and a sixfold increased peel strength than plain PAA, together with good biocompatibility. Furthermore, when mesoporous silica nanoparticles (MSNs) with active agent loading into their pores are incorporated instead of SSNs, the active agent can be released from the hydrogel sheet in a sustained or temperature-sensitive manner, indicating that the system is potentially applicable to transdermal drug delivery system with no additional adhesive. A novel hydrogel sheet is developed, blending cellulose nanofibers and silica nanoparticles with an acrylic acid base. This composition enhances both mechanical and adhesive properties, making it a promising tool for non-invasive drug delivery, allowing precise, skin-friendly medication release without additional adhesives. image | Nam, Kibeom; Park, Ju Hyang; Kim, Eon Ji; Kim, Jong Ryeol; Min, Yuho; Hyun, Dong Choon; Lee, Dong Yun | Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Korea Text Dev Inst, Daegu 41842, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | 57210467782; 57189227357; 58122045100; 57338133300; 36782804100; 15834575400; 57211001605 | dong.hyun@knu.ac.kr;dongyunlee@knu.ac.kr; | ADVANCED MATERIALS INTERFACES | ADV MATER INTERFACES | 2196-7350 | 11 | 10 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 4.4 | 32.8 | 0.32 | 2025-05-07 | 1 | 1 | adhesive; cellulose nanofiber; hydrogel; poly(acrylic acid) (PAA); silica nanoparticle | CELLULOSE; TOUGH; PATCHES; ACID | adhesive; cellulose nanofiber; hydrogel; poly(acrylic acid) (PAA); silica nanoparticle | Adhesives; Carboxylic Acids; Construction; Hydrogen Bonds; Photopolymerization; Sheets; Silica; Adhesives; Biocompatibility; Carboxylic acids; Controlled drug delivery; Ductile fracture; Fabrication; Hydrogen bonds; Nanocellulose; Nanofibers; Photopolymerization; Silica nanoparticles; Targeted drug delivery; Adhesive properties; Cellulose nanofibers; Large-sized; Mechanical; Modified cellulose; Physical cross-linkers; Poly(acrylic acid); Poly(acrylic acid) (PAA); Silica nanoparticles; Solid silica; Hydrogels | English | 2024 | 2024-04 | 10.1002/admi.202300778 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Lifting B-subnormal operators | We study B-operators (Brownian-type operators), which are upper triangular 2 x 2 block matrix operators with entries satisfying some algebraic constraints. We establish a lifting theorem stating that any B-subnormal operator, i.e., a B-operator with subnormal (2,2) entry, lifts to a B-normal operator, i.e., a B-operator with normal (2,2) entry, where lifting is understood in the sense of extending entries of the block matrices representing the operators in question. The spectral inclusion and the filling-in-holes theorems are obtained for such operators. | Chavan, Sameer; Jablonski, Zenon Jan; Jung, Il Bong; Stochel, Jan | Indian Inst Technol, Dept Math & Stat, Kanpur, India; Kyungpook Natl Univ, Dept Math, Daegu 702701, South Korea; Uniwersytet Jagiellonski, Inst Matemat, PL-30348 Krakow, Poland | chavan@iitk.ac.in;Zenon.Jablonski@im.uj.edu.pl;ibjung@knu.ac.kr;Jan.Stochel@im.uj.edu.pl; | STUDIA MATHEMATICA | STUD MATH | 0039-3223 | 1730-6337 | 277 | 2 | SCIE | MATHEMATICS | 2024 | 0.9 | 32.8 | 0 | upper triangular 2 x 2 block matrix; subnormal operator; normal operator; lifting; spectral inclusion | M-ISOMETRIC TRANSFORMATIONS; HYPERINVARIANT SUBSPACES; INVARIANT SUBSPACES; HILBERT-SPACE | English | 2024 | 2024 | 10.4064/sm231005-9-6 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Mixing is hard for triangle-free reflexive graphs☆ | In the problem Mix(H) one is given a graph G and must decide if the Hom-graph Hom(G, H) is connected. We show that if H is a triangle-free reflexive graph with at least one cycle, Mix(H) is coNP-complete. The main part of this is a reduction to the problem NonFlat(H) for a simplicial complex H, in which one is given a simplicial complex G and must decide if there are any simplicial maps phi from G to H under which some 1-cycles of G maps to homologically nontrivial cycle of H. We show that for any reflexive graph H, if the clique complex H of H has a free, nontrivial homology group H1(H), then NonFlat(H) is NP-complete.(c) 2023 Elsevier Ltd.

| ○ | ○ | Article | Association between Antacid Exposure and Risk of Interstitial Lung Diseases | Background: The mechanisms leading to lung fibrosis are still under investigation. This study aimed to demonstrate whether antacids could prevent the development of interstitial lung disease (ILD). Methods: This population -based longitudinal cohort study was conducted between January 2006 and December 2010 in South Korea. Eligible subjects were >= 40 years of age, exposed to proton pump inhibitors (PPI)+/- histamine-2 receptor antagonists (H-2 blockers) or H-2 blockers only, and had no history of ILD between 2004 and 2005. Exposure to antacids was defined as the administration of either PPI or H-2 receptor antagonists for >14 days, whereas underexposure was defined as antacid treatment administered for less than 14 days. Newly developed ILDs, including idiopathic pulmonary fibrosis (IPF), were counted during the 5 -year observation period. The association between antacid exposure and ILD development was evaluated using adjusted Cox regression models with variables, such as age, sex, smoking history, and comorbidities. Results: The incidence rates of ILD with/without antacid use were 43.2 and 33.8/100,000 person -years, respectively and those of IPF were 14.9 and 22.9/100,000 person -years, respectively. In multivariable analysis, exposure to antacid before the diagnosis of ILD was independently associated with a reduced development of ILD (hazard ratio [HR], 0.57; 95% confidence interval [CI], 0.45 to 0.71; p<0.001), while antacid exposure was not associated with development of IPF (HR, 0.88; 95% CI, 0.72 to 1.09; p=0.06). Conclusion: Antacid exposure may be independently associated with a decreased risk of ILD development. | Bae, Soohyun; Loloci, Gjustina; Lee, Dong Yoon; Jang, Hye Jin; Jeong, Jihyeon; Choi, Won-Il | Hanyang Univ, Coll Med, Myongji Hosp, Dept Internal Med, Goyang, South Korea; German Hosp Tirana, Tirana, Albania; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Hanyang Univ, Coll Med, Myongji Hosp, Dept Internal Med, 55 Hwasu ro 14beon gil, Goyang 10475, South Korea | ; Lee, DongYoon/KFR-2934-2024; Jang, Hye Jin/IZE-4223-2023 | 57200222489; 56394529600; 57309281000; 57222352277; 57209972988; 7402516121 | wichoi7572@hanyang.ac.kr; | TUBERCULOSIS AND RESPIRATORY DISEASES | TUBERC RESPIR DIS | 1738-3536 | 2005-6184 | 87 | 2 | ESCI | RESPIRATORY SYSTEM | 2024 | 3 | 32.9 | 0 | 2025-05-07 | 0 | 0 | Interstitial Lung Disease; Idiopathic Pulmonary Fibrosis; Antacid Exposure; Incidence | IDIOPATHIC PULMONARY-FIBROSIS; PROTON PUMP INHIBITORS; GASTROESOPHAGEAL-REFLUX; PREVALENCE; THERAPY; ASPIRATION; SURVIVAL | Antacid Exposure; Idiopathic Pulmonary Fibrosis; Incidence; Interstitial Lung Disease | antacid agent; adult; aged; Article; cerebrovascular disease; chronic kidney failure; chronic obstructive lung disease; clinical feature; clinical observation; cohort analysis; controlled study; diabetes mellitus; disease association; disease course; drug exposure; eligibility criteria; female; fibrosing alveolitis; gastroesophageal reflux; heart infarction; human; hypertension; incidence; interstitial lung disease; longitudinal study; lung fibrosis; major clinical study; male; medical history; middle aged; pathogenesis; peptic ulcer; risk; sensitivity analysis; smoking; South Korea; tuberculosis; very elderly | English | 2024 | 2024-04 | 10.4046/trd.2023.0093 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Characterization of Yeast Protein Hydrolysate for Potential Application as a Feed Additive | Yeast protein can be a nutritionally suitable auxiliary protein source in livestock food. The breakdown of proteins and thereby generating high-quality peptide, typically provides nutritional benefits. Enzyme hydrolysis has been effectively uesed to generate peptides; however, studies on the potential applications of different types of enzymes to produce yeast protein hydrolysates remain limited. This study investigated the effects of endo- (alcalase and neutrase) and exotype (flavourzyme and prozyme 2000P) enzyme treatments on yeast protein. Endotype enzymes facilitate a higher hydrolysis efficiency in yeast proteins than exotype enzymes. The highest degree of hydrolysis was observed for the protein treated with neutrase, which was followed by alcalase, prozyme 2000P, and flavourzyme. Furthermore, endotype enzyme treated proteins exhibited higher solubility than their exotype counterparts. Notably, the more uniform particle size distribution was observed in endotype treated yeast protein. Moreover, compared with the original yeast protein, the enzymatic protein hydrolysates possessed a higher content of beta-sheets structures, indicating their higher structural stability. Regardless of enzyme type, enzyme treated protein possessed a higher total free amino acid content including essential amino acids. Therefore, this study provides significant insights into the production of protein hydrolysates as an alternative protein material. | Min, Ju Hyun; Lee, Yeon Ju; Kang, Hye Jee; Moon, Na Rae; Park, Yong Kuk; Joo, Seon-Tea; Jung, Young Hoon | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Armored Fresh Food Tech Co, Seoul 06693, South Korea; Gyeongsang Natl Univ, Inst Agr & Life Sci, Div Appl Life Sci BK21 Four, Jinju 52828, South Korea | ; Jung, Young Hoon/F-1703-2013; Jung, Young/F-1703-2013 | 57217835247; 58700074500; 57219656318; 59146617900; 59146778900; 7101656375; 55550063700 | younghoonjung@knu.ac.kr; | FOOD SCIENCE OF ANIMAL RESOURCES | FOOD SCI ANIM RESOUR | 2636-0772 | 2636-0780 | 44 | 3 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2024 | 3.7 | 32.9 | 0.73 | 2025-04-16 | 3 | 3 | yeast protein; endoprotease; exoprotease; hydrolysis; alternative protein | PERFORMANCE; SUPPLEMENTATION; SOLUBILITY; RESPONSES | alternative protein; endoprotease; exoprotease; hydrolysis; Keywords yeast protein | English | 2024 | 2024 | 10.5851/kosfa.2024.e33 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Synoptic circulation factors associated with wintertime high-PM2.5 concentrations in seoul, Republic of Korea: Their interpretations and applications | Many studies have explored atmospheric circulation fields associated with high particulate matter (PM) events, but only a few studies have evaluated the relative importance of meteorological variables in the circulation fields. In this study, we applied factor analysis method to examine meteorological variables related to the synoptic pattern of high-PM2.5 episodes (i.e., days with daily averaged PM2.5 concentration exceeding 35 mu gm 3) in Seoul, Republic of Korea, during the winter season of 2004-2018. Here, we highlight three independent key factors (F1, F2, and F3) associated with high-PM2.5 concentrations. F1 is related to temperature (T) and meridional wind (V) at 850 hPa and 1000 hPa (i.e., T850, T1000, V850, and V1000) and temperature and geopotential height (Z) at 500 hPa (i.e., T500 and Z500). It is the most strongly correlated with T850, indicating an increase in thermal stability over Korea during high-PM2.5 events due to vertically reduced atmospheric ventilation. Meanwhile, F2 is significantly related to the geopotential height and zonal wind (U) at 850 hPa and 1000 hPa (i.e., Z850, Z1000, U850, and U1000). This indicates a dynamically stable condition due to the anomalous easterlies caused by the vertically elongated anticyclone over the northern part of the Korean Peninsula. Finally, F3 is positively associated with zonal and meridional winds at 500 hPa (i.e., U500 and V500). This means that relatively strong winds in the low-to-mid troposphere contribute to high-PM2.5 concentrations by transporting pollutants from the industrial regions of eastern China to Korea. We also examined the possible influence of climate change on high-PM2.5 concentrations based on the aforementioned three factors. According to the various shared socioeconomic pathway (SSP) scenarios, F1 increases significantly for all SSP scenarios compared to F2 and F3, indicating that synoptic patterns related to F1 occur frequently, leading to a favorable condition for high-PM2.5 concentrations. Thus, our finding suggests that climate change alone could worsen air quality in the future even without changes in direct PM2.5 emissions. | Oh, Hye-Ryun; Park, Doo-Sun R.; Kim, Dasol; Ho, Chang-Hoi; Lee, Seungmin | Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu, South Korea; Univ Florida, Dept Geog, 3141 Turlington Hall 330 Newell Dr, Gainesville, FL 32611 USA; Ewha Womans Univ, Dept Climate & Energy Syst Engn, Seoul, South Korea; Korea Environm Inst, Sejong, South Korea | Ho, Chang-Hoi/H-8354-2015; Kim, Dasol/GWR-1499-2022; Park, Doo-Sun/U-9448-2019 | 35409958300; 37117659000; 56420697800; 7404653593; 57192520138 | dasol.kim@ufl.edu; | ATMOSPHERIC ENVIRONMENT | ATMOS ENVIRON | 1352-2310 | 1873-2844 | 325 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES | 2024 | 3.7 | 32.9 | 1.68 | 2025-05-07 | 5 | 5 | Factor analysis; High-PM2.5; Synoptic pattern; Future projection | PARTICULATE MATTER; AIR-QUALITY; PM2.5 POLLUTION; URBAN AIR; CHINA; MORTALITY; FINE; HAZE; PARTICLES; EPISODES | Factor analysis; Future projection; High-PM<sub>2.5</sub> ; Synoptic pattern | China; Seoul [South Korea]; South Korea; Climate change; Multivariant analysis; Wind; 850-hPa; Factors analysis; Future projections; Geo-potential heights; High-particulate matter2.5; Meridional winds; Meteorological variables; Particulate Matter; Republic of Korea; Synoptic pattern; air quality; anticyclone; atmospheric circulation; climate change; factor analysis; geopotential; particulate matter; zonal wind; adult; air quality; article; China; climate change; factor analysis; human; Korea; particulate matter; particulate matter 2.5; signal transduction; South Korea; temperature; thermostability; troposphere; wind; winter; Factor analysis | English | 2024 | 2024-05-15 | 10.1016/j.atmosenv.2024.120444 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Association between Conversion to Shockable Rhythms and Survival with Favorable Neurological Outcomes for Out-of-Hospital Cardiac Arrests | BackgroundThe initial cardiac rhythm in out-of-hospital cardiac arrest (OHCA) portends different prognoses and affects treatment decisions. Initial shockable rhythms are associated with good survival and neurological outcomes but there is conflicting evidence for those who initially present with non-shockable rhythms. The aim of this study is to evaluate if OHCA with conversion from non-shockable (i.e., asystole and pulseless electrical activity) rhythms to shockable rhythms compared to OHCA remaining in non-shockable rhythms is associated with better survival and neurological outcomes.MethodOHCA cases from the Pan-Asian Resuscitation Outcomes Study registry in 13 countries between January 2009 and February 2018 were retrospectively analyzed. Cases with missing initial rhythms, age <18 years, presumed non-medical cause of arrest, and not conveyed by emergency medical services were excluded. Multivariable logistic regression analysis was performed to evaluate the relationship between initial and subsequent shockable rhythm, survival to discharge, and survival with favorable neurological outcomes (cerebral performance category 1 or 2).ResultsOf the 116,387 cases included. 11,153 (9.6%) had initial shockable rhythms and 9,765 (8.4%) subsequently converted to shockable rhythms. Japan had the lowest proportion of OHCA patients with initial shockable rhythms (7.3%). For OHCA with initial shockable rhythm, the adjusted odds ratios (aOR) for survival and good neurological outcomes were 8.11 (95% confidence interval [CI] 7.62-8.63) and 15.4 (95%CI 14.1-16.8) respectively. For OHCA that converted from initial non-shockable to shockable rhythms, the aORs for survival and good neurological outcomes were 1.23 (95%CI 1.10-1.37) and 1.61 (95%CI 1.35-1.91) respectively. The aORs for survival and good neurological outcomes were 1.48 (95%CI 1.22-1.79) and 1.92 (95%CI 1.3 - 2.84) respectively for initial asystole, while the aOR for survival in initial pulseless electrical activity patients was 0.83 (95%CI 0.71-0.98). Prehospital adrenaline administration had the highest aOR (2.05, 95%CI 1.93-2.18) for conversion to shockable rhythm.ConclusionIn this ambidirectional cohort study, conversion from non-shockable to shockable rhythm was associated with improved survival and neurologic outcomes compared to rhythms that continued to be non-shockable. Continued advanced resuscitation may be beneficial for OHCA with subsequent conversion to shockable rhythms. | Ho, Andrew Fu Wah; Lee, Kai Yi; Nur, Shahidah; Fook, Stephanie Chong; Pek, Pin Pin; Tanaka, Hideharu; Sang, Do Shin; Chow, Patrick In-Ko; Tan, Benjamin Yong-Qiang; Lim, Shir Lynn; Ma, Matthew Huei-Ming; Ryoo, Hyun Wook; Lin, Chih-Hao; Kuo, Chan-Wei; Kajino, Kentaro; Ong, Marcus Eng Hock | Singapore Gen Hosp, Dept Emergency Med, Singapore, Singapore; Duke NUS Med Sch, Prehosp & Emergency Res Ctr, Singapore, Singapore; Minist Hlth Holdings, Phys, Singapore, Singapore; Duke NUS Med Sch, Prehosp Emergency & Res Ctr, Singapore, Singapore; Kokushikan Univ, Grad Sch, Dept Emergency Med Serv Syst, Tokyo, Japan; Kokushikan Univ, Res Inst Disaster Prevent EMS & Rescue, Tokyo, Japan; Seoul Natl Univ, Dept Emergency Med, Coll Med, Seoul, South Korea; Seoul Natl Univ Hosp Biomed, Res Inst, Lab Emergency Med Serv, Seoul, South Korea; Natl Taiwan Univ, Dept Emergency Med, Natl Taiwan Univ Hosp, Coll Med, Taipei, Taiwan; Natl Univ Hlth Syst, Dept Med, Div Neurol, Singapore, Singapore; Natl Univ Heart Ctr, Dept Cardiol, Singapore, Singapore; Natl Taiwan Univ Hosp, Dept Emergency Med, Yunlin Branch, Touliu, Taiwan; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Emergency Med, Daegu, South Korea; Natl Cheng Kung Univ, Natl Cheng Kung Univ Hosp, Coll Med, Dept Emergency Med, Tainan, Taiwan; Chang Gung Mem Hosp, Dept Emergency Med, Taoyuan, Taiwan; Kansai Med Univ, Dept Emergency & Crit Care Med, Hirakata, Osaka, Japan; Duke NUS Med Sch, Hlth Serv & Syst Res, Singapore, Singapore | ; 田中, 秀治/ABC-8931-2021; Ho, Andrew/F-6213-2016; Ho, Andrew Fu Wah/F-6213-2016; Tan, Yongcheng/AAR-4344-2020; Ong, Marcus/LNP-4888-2024 | 55701539100; 58839335100; 58362158000; 58363412400; 57559394400; 7406594639; 57049712400; 58360902900; 56765135000; 48061164200; 26039292700; 55350557500; 56181886400; 55633025300; 8411109200; 7006449334 | lee.kaiyi96@gmail.com; | PREHOSPITAL EMERGENCY CARE | PREHOSP EMERG CARE | 1090-3127 | 1545-0066 | 28 | 1 | SCIE | EMERGENCY MEDICINE;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2024 | 2 | 33.0 | 2.29 | 2025-04-16 | 4 | 3 | PULSELESS ELECTRICAL-ACTIVITY; ASIAN RESUSCITATION OUTCOMES; CARDIOPULMONARY-RESUSCITATION; VENTRICULAR-FIBRILLATION; PROGNOSTIC-SIGNIFICANCE; SINGLE-CENTER; EPINEPHRINE; ASYSTOLE; ETIOLOGY; TRENDS | Adolescent; Cardiopulmonary Resuscitation; Cohort Studies; Electric Countershock; Emergency Medical Services; Humans; Out-of-Hospital Cardiac Arrest; Registries; Retrospective Studies; adolescent; cardioversion; cohort analysis; emergency health service; human; out of hospital cardiac arrest; register; resuscitation; retrospective study | English | 2024 | 2024-01-02 | 10.1080/10903127.2023.2212039 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Comparative biomechanical analysis of reconstruction and cephalomedullary nails in the treatment of osteoporotic subtrochanteric fractures | Introduction: This study aimed to compare the biomechanical properties of two types of intramedullary nails - reconstruction nails (RCN) and cephalomedullary nails (CMN) - each with different proximal fixations, in a model of an osteoporotic subtrochanteric femoral fracture. This study focused on assessing stiffness and load to failure of RCN and CMN nails to provide insight into their clinical applications in osteoporotic fracture treatments. Materials and Methods: Ten synthetic osteoporotic femoral models were used to generate a comminuted subtrochanteric fracture model. Five femurs were fixed using an RCN, and the remaining five were fixed using a CMN. The constructs were subjected to axial compression to measure their structural stiffness, load to failure, and failure modes. Results: The CMN group demonstrated a slightly higher load to failure (mean, 2250 N) than the RCN group (mean, 2100 N), which was statistically significant ( p = 0.008). However, the stiffness in both groups was statistically similar (RCN, 250 N/mm; CMN, 255 N/mm; p = 0.69). Both groups showed a load to failure exceeding 1500 N, a typically exerted load on the femoral head by a 75 kg individual. The failure patterns differed, with CMN failures starting at the nail insertion area and RCN failures starting at the reconstruction screw area. Conclusion: The RCN offers stiffness comparable to that of the CMN; although its load to failure is slightly lower than that of the CMN, it still exceeds the physiological tolerance limit. These findings suggest that the RCN is a viable alternative for treating osteoporotic subtrochanteric fractures. | Yoon, Yong-Cheol; Kim, Joon-Woo; Kim, Tae-Kong; Oh, Chang-Wug; Park, Kyeong-Hyeon; Lee, Jin-Han | Gachon Univ, Coll Med, Trauma Ctr, Orthoped Trauma Div, Incheon, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Orthoped Surg, 130 Dongdeok Ro, Daegu 41944, South Korea; Yonsei Univ, Severance Childrens Hosp, Dept Orthoped Surg, Coll Med, Seoul, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Joint Inst Regenerat Med, Biomed Res Inst, Daegu, South Korea | Kim, Jin-Seok/AAK-5424-2020; Park, KyeongHyeon/KEH-4919-2024; Park, Jung Hyun/HJA-3755-2022; Oh, Chang-Wug/AAO-4602-2021; Yong-Cheol, Yoon/HPD-8077-2023 | 37082544400; 22951329000; 57202157782; 22135834200; 56969984400; 57202149598 | cwoh@knu.ac.kr; | INJURY-INTERNATIONAL JOURNAL OF THE CARE OF THE INJURED | INJURY | 0020-1383 | 1879-0267 | 55 | 6 | SCIE | CRITICAL CARE MEDICINE;EMERGENCY MEDICINE;ORTHOPEDICS;SURGERY | 2024 | 2 | 33.0 | 0.95 | 2025-05-07 | 1 | 1 | Osteoporotic subtrochanteric fracture; Intramedullary nailing; Cephalomedullary nail; Reconstruction nail; Synthetic bone; Biomechanical study | FEMUR FRACTURES; CADAVERIC FEMURS; FIXATION; INTRAMEDULLARY; BLADE; SCREW; BREAKAGE; PLATE; MODEL | Biomechanical study; Cephalomedullary nail; Intramedullary nailing; Osteoporotic subtrochanteric fracture; Reconstruction nail; Synthetic bone | Biomechanical Phenomena; Bone Nails; Fracture Fixation, Intramedullary; Fractures, Comminuted; Hip Fractures; Humans; Materials Testing; Osteoporotic Fractures; Weight-Bearing; Article; biomechanics; comminuted fracture; comparative effectiveness; compression; controlled study; device failure analysis; experimental study; failure mode and effects analysis; femoral head; femoral head fracture; femoral neck fracture; femur intertrochanteric fracture; femur subtrochanteric fracture; fracture fixation; fragility fracture; intramedullary nailing; load bearing; mechanical test; rigidity; biomechanics; comparative study; devices; fragility fracture; hip fracture; human; intramedullary nailing; materials testing; pathophysiology; physiology; procedures; surgery; weight bearing | English | 2024 | 2024-06 | 10.1016/j.injury.2024.111512 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Review | Critical size bone defects managed with modern techniques of bone transport: An update | Bone transport is one of several techniques that has been proven to be effective in addressing critical bone loss. While it was first described over 100 years ago, modifications to this technique coupled with advances in technology have allowed us to perform bone transport with higher success rates and reduced complication rates. Modern techniques of bone transport aim to shorten the duration of time an external fixator is utilized to reduce its associated complications and burden to patients. We present an update on modern techniques of bone transport for critical size defects and methods to shorten the external fixation time. | Seng, Daniel W. .
